I don't have any self-employed clients with ACA insurance, so I wonder what caused this problem. 

Did the Intuit programmers decide, "People are too stupid to carry over the excess credit to the SEHI deduction, so we'll have to do it for them automatically?"

Why didn't they do that with Medicare premiums?

Does the amount of the excess premium credit depend on AGI, so it's a loop like figuring IRA deduction with taxable Social Security?  

I'm just waiting to see how this prices out for next year's package.  Having sold us something we might not want -- an automatic link from excess premium credit to SEHI -- now they have to sell us a fix that turns it off if the same forgiveness is enacted retroactively for 2021.
